important because some advanced refrigeration systems that reduce refrigerant use can have higher energy requirements than conventional systems, eroding some of the net climate benefits of these technologies (ICF Consulting , US EPA ). 3 For a typical store, this amounts to about 2 to 3 million kWh of electricity consumption per year. Energy As this book is on Solar Energy, it is good to start the discussion with some general thoughts on Energy. We will begin with a quote from The Feynman Lectures on Physics. There is a fact, or if you wish, a law, governing all natural phenomena that are known to date. There is no known exception to this law—it is exact so far as we know.
and theory of refrigeration, the components of mechanical refrigeration systems, and the types of refrigerants and associated equipment. Also covered in this chapter are the methods used for installing, maintaining, and repairing refrigeration equipment, including domestic refrigerators and freezers. Chapter 18 Refrigeration Plant and Mine Air Conditioning Systems Malcolm J. McPherson 3 can no longer remain in the liquid phase but burst free to form a vapour or gas (Section ).
2. Calculate/estimate the refrigeration energy provided by the centralised system. 3. The difference between these two numbers would be ‘unaccounted for heat gain’. Figure 1 represents a typical energy balance for a cool store and two other refrigeration processes in which the system is providing 30% more refrigeration energy than. To make our cyber space refrigeration system a little more realistic lets separate the evaporator away from the compressor section and put it inside an insulated box. The left over components can now be called a Condensing Unit. The insulated box does not conduct heat well.
